Future releases of pacc may be autoconfiscated.

For this release:

- to build pacc, and perform the pacc3 basic sanity check: make

- to build the documentation: make doc

- to run the test suite: make check

- to run an individual test: cd test; ./run.sh emit/mk-class0.c

Nothing is automatically installed; here's a reasonable set of commands to copy
and paste for a FHS-compliant system.

 prefix=/usr/local
 cp pacc $prefix/bin
 cp doc/pacc.man $prefix/share/man/man1/pacc.1
 cp doc/pacc.info $prefix/share/info && gzip $prefix/share/info/pacc.info
